Hacking [Question] Boot luma (and NTRBoot) without top screen (speakers)

[Kubas_inko]

Don't know if this goes here or to hardware section, so please move it in that case.
As you can see here, I have fully working New 3DS, with a desoldered broken connector (for speakers, 3D and probably bightness). Without those being connected, 3DS wont boot at all. So my question is, is there any way, how to go around it, so that I can at least get some info from the console (personally to unban my friends working console)?
Thank you for any response.
